Question by RedWarrior · Mar 19, 2013 at 10:31 PM · c#rotationpositionlerp

How do I lerp the position and rotation?

Hi guys, I have created this script which allows my camera to lerp between positioned way points. The position works fine but I can work out how to get rotation to work. I keep getting, Cannot implicitly convert type UnityEngine.Quaternion' to UnityEngine.Transform'

Here is my script

 using UnityEngine;
 using System.Collections;
 
 public class CameraZoomControl : MonoBehaviour 
 {
     
     public GameObject LookHere;
     
     public Transform CameraTransform;
     
     public Transform[] waypoints;
     
     public Vector3 camPosOld;
     public Vector3 camPosCurrent;
     public Vector3 camPosNew;
     
     public Transform camRotationOld;
     public Transform camRotationCurrent;
     public Transform camRotationNew;
     
     
     public int wayPointNo = 0;
     
     void Start () 
     {
         camPosCurrent = transform.position;
         camRotationCurrent = transform.rotation;
         
         camPosNew = waypoints[wayPointNo].position;
         camPosNew = waypoints[wayPointNo].rotation;
         
     }
     
     void Update () 
     {
         
         if (CameraTransform != null)
         CameraTransform.LookAt(LookHere.transform);
         
         
         
         camPosOld = camPosCurrent;
         camRotationOld = camRotationCurrent;
         
         
         camPosCurrent = Vector3.Lerp (camPosOld, camPosNew, Time.deltaTime * 0.1f);
         camRotationCurrent = Quaternion.Lerp (camPosOld, camPosNew, Time.deltaTime * 0.1f);
         
         
         
         transform.position = camPosCurrent;
         transform.rotation = camRotationCurrent;
         
         
         
         if (Vector3.Distance(camPosCurrent, waypoints[wayPointNo].position) <= 1f)
         {
             wayPointNo++;
             if (wayPointNo > 3)
                 wayPointNo = 0;
             
             camPosNew = waypoints[wayPointNo].position;
             camRotationNew = waypoints[wayPointNo].rotation;
             
         }
 
     }
 }


Thanks in advance for any help.

You need to define camRotationNew, camRotationOld, camRotationCurrent as Quaternions, not Transforms...

The clue's in the error message! ;)
